Im trying to find a catback exhaust for my car. It looks like the only one I can find would be a MagnaFlow for close to $600 which seems a little much considering I bought one for my t-bird a few years ago for around $280. Do any other quality brands make an exhaust for my Mazda? And if so I don't want it to sound like a tuner car. I like a deep throaty sound. Thanks.
